Frequently Asked Questions (FAQ)

Q: Can the 0ZRN0900FF1A directly replace the MF-RHT900-0-14 in existing designs?

A: Yes. The 0ZRN0900FF1A is a parametric equivalent with identical electrical ratings (16V, 9A hold current, 16.5A trip current), identical mechanical dimensions (radial disc, 0.201" lead spacing), and identical operating temperature range (-40°C to 125°C). Both components are polymeric PTC resettable fuses with AEC-Q200 qualification.

Q: Are there differences in approval certifications between these parts?

A: Both components carry TUV and cURus approvals. The MF-RHT900-0-14 includes cUL certification, while the 0ZRN0900FF1A includes UL certification. Applications requiring specific approval agency documentation should verify alignment with system requirements before substitution.

Q: Do these components have identical physical dimensions?

A: Yes. Both components have identical dimensions: 0.650" L x 0.118" W (16.50mm x 3.00mm), maximum seated height of 1.012" (25.70mm), and lead spacing of 0.201" (5.10mm). They are mechanically interchangeable in through-hole radial disc mounting applications.

Q: What is the difference in resistance specifications between these parts?

A: There is no difference. Both components have identical initial resistance (Ri) of 7.4 mOhms minimum and post-trip resistance (R1) of 17 mOhms maximum. Electrical performance characteristics are equivalent.

Q: Are both components suitable for automotive applications?

A: Yes. Both the MF-RHT900-0-14 and 0ZRN0900FF1A carry AEC-Q200 qualification, indicating suitability for automotive-grade applications with specified reliability and performance standards.

Q: What is the operating temperature range for these components?

A: Both components operate across the identical temperature range of -40°C to 125°C, supporting applications in standard industrial and automotive environments.

Q: How do the trip characteristics compare?

A: Both components have identical trip characteristics: 16.5A trip current (It) with a 10-second time to trip. This ensures consistent overcurrent protection behavior in circuit applications.
